ATTACHMENT FOR TELEPHONES.

To all whom z't-htay concern I Be it known that I, WILLIAM A. SCHMELZ, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, havev invented certain new and useful Improvemerits in Attachments for Telephones, of which the following is a specification, referones being bad therein to the accompanying.

drawing.

This invention relates to an attachment for telephones, and the primary object of my invention is to furnish the receiver of the telephone with an attachment that can be connected to the ear whereby a conversation can be carried on over the telephone without the necessity of holding the receiver to the ear, it being only necessary to slightly elevate the receiver to establish a talking circuit.

A further object of this invention is to provide an attachment that can be adjustably established for long conversations over a telephone, it being possible to remove the receivenlay" the same upon a table or other support and carry on the conversation, with 'both hands free, thus permitting of notations being made or the hands used for other purposes.

With the above the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing wherein:

Figure 1 is aside elevation of a telephone provided with the attachment, Fig. 2 is an elevation of the ear piece, Fig. 3 1s a vertical sectional view of the same, Fig.4 is an enlarged sectional view of the receiver piece, and, Fig. 5' is a perspective View of a detached clamp for the receiver.

The receiver piece comprises an exteriorly screw threaded sleeve 1 having the outer face thereof provided with. a bead or rimfl over which-is mount-ed the end of a flexible tube 3. The opposite end of the tube is mounted over the nipple t of a hollow ear piece 5. The ear piece is cupped shaped and has an opening 6 providing clearance for' the ear, said opening being oblong with one end thereof open and the opposite end terminating in proximity to the top of the ear piece, whereby said ear piece can be hung or Specification of Letters Patent.

and other objects in view,

suspended upon the crest of the car. This car piece is preferably made of hard rubber or other light and durable sound proof material.

Adjustably mounted upon the sleeve 1 is a cupped shaped receiver piece 7 preferably made of hard rubber, said piecehaving an annular groove 8 for a ring or gasket 9'tl1at engages the end 10 of a receiver 11. Adjustably mounted upon the sleeve 1 is a collar 12 having diametrically opposedue silient clamping arms 13, said arms having inwardly bent ends'lt for engaging the end 10 of the receiver 11 and retaining the rcceiver piece in engagement therewith.

The receiver 11 can form part of an ordinary desk or wall telephone 15, and when thereceiver 11 is removed from the hook or arm 16 of the telephone, a circuit is established that permits of the person readily carrying on a conversation over the "tele phone.

With the receiver piece clamped upon the receiver, the sounds emitted by the receiver are transmitted to the ear piece by the tube 3, and said ear piece relieves the user of the telephone of holding the receiver 11 during a conversation.

What I claim is:-

1. An attachment for telephones comprising a threaded sleeve, a cup-shaped member attachably mounted upon said sleeve and capable of bearing against the free end of a telephone receiver, resilient clamping arms fixed to and projecting from said sleeve and capable of engaging with the receiver of the telephone for maintaining said cup shaped member in position, and sound conducting means attached to said sleeve. 2. An attachment-for telephones comprising a sleeve, a cup-shaped member mounted upon said sleeve and capable of bearing against the free end of a telephone receiver, clamping arms carried by the sleeve and capable of engaging with the receiver of the telephone for maintaining said cup-shaped member in position, and sound conducting means connected to said sleeve.

In testimony whereof I allix my signature in the presence of tWONVltIlQSSGS.
